In this contribution, we analyse the dielectric response of a simple RC model composed of single RC circuits (relaxors) with the exponential response. The relaxation time of a single relaxor is defined by the product of resistance and capacitance: τ = RC . We present two hypothetical algorithms of generating gaussian input function, one with fluctuation of a density decay, and the other one with normalized density. Both of them enable to obtain a different impedance response of the system. An algorithm of input function creation is crucial to generating the response of the presented model.
